API\n\nWebhooks を使用すると、Synapse でイベントが発生した際に HTTP コールバックを受信できます。外部自動化のトリガー、通知の送信、他システムへの同期に最適です。\n\n## エンドポイント\n\n### POST /webhooks\n\n新しい Webhook を登録します。\n\n```bash\ncurl -X POST https://synapse.schaefer.zone/webhooks \\\n  -H \"Authorization: Bearer YOUR_MIND_KEY\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"url\": \"https://my-app.com/webhook\",\n    \"events\": \"memory.*\",\n    \"secret\": \"my-hmac-secret-min-8-chars\"\n  }'\n```\n\nレスポンス：\n\n```json\n{\n  \"id\": \"wh_001\",\n  \"url\": \"https://my-app.com/webhook\",\n  \"events\": [\"memory.*\"],\n  \"enabled\": true,\n  \"created_at\": \"2026-06-27T...\"\n}\n```\n\n### GET /webhooks\n\n現在の mind のすべての Webhook を一覧表示します。\n\n```bash\ncurl -H \"Authorization: Bearer YOUR_MIND_KEY\" \\\n     https://synapse.schaefer.zone/webhooks\n```\n\n### GET /webhooks/:id\n\n単一の Webhook を取得します。\n\n```bash\ncurl -H \"Authorization: Bearer YOUR_MIND_KEY\" \\\n     https://synapse.schaefer.zone/webhooks/wh_001\n```\n\n### PUT /webhooks/:id\n\nWebhook を更新します（URL、events、secret、enabled フラグ）。\n\n```bash\ncurl -X PUT https://synapse.schaefer.zone/webhooks/wh_001 \\\n  -H \"Authorization: Bearer YOUR_MIND_KEY\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"enabled\": false}'\n```\n\n### DELETE /webhooks/:id\n\nWebhook を削除します。\n\n```bash\ncurl -X DELETE -H \"Authorization: Bearer YOUR_MIND_KEY\" \\\n     https://synapse.schaefer.zone/webhooks/wh_001\n```\n\n## イベント種別\n\n| パターン | 発生タイミング |\n|---------|------------|\n| `memory.*` | 任意のメモリイベント |\n| `memory.store` | 新規メモリの保存 |\n| `memory.update` | メモリの更新 |\n| `memory.delete` | メモリの削除 |\n| `chat.*` | 任意のチャットイベント |\n| `chat.message_received` | 人間からの新規メッセージ |\n| `task.*` | 任意のタスクイベント |\n| `task.created` | 新規タスクの作成 |\n| `task.completed` | タスクの完了マーク |\n| `*` | 全イベント |\n\n## Webhook ペイロード\n\nイベント発生時、Synapse はあなたの URL に POST リクエストを送信します。\n\n```json\n{\n  \"event\": \"memory.store\",\n  \"timestamp\": \"2026-06-27T...\",\n  \"mind_id\": \"m_xyz789\",\n  \"data\": {\n    \"id\": \"mem_001\",\n    \"category\": \"fact\",\n    \"key\": \"user_name\",\n    \"content\": \"Michael Schäfer\"\n  }\n}\n```\n\n## 署名検証\n\n`secret` を設定すると、Synapse は各ペイロードを HMAC-SHA256 で署名します。\n\n```\nX-Synapse-Signature: sha256=<hex-hmac>\n```\n\nハンドラで検証します：\n\n```python\nimport hmac, hashlib\n\ndef verify_signature(payload_body: bytes, signature: str, secret: str) -> bool:\n    expected = hmac.new(\n        secret.encode(),\n        payload_body,\n        hashlib.sha256\n    ).hexdigest()\n    return hmac.compare_digest(f\"sha256={expected}\", signature)\n```\n\n## パターン：リアルタイム同期\n\n```python\n# Your webhook handler\n@app.post(\"/webhook\")\nasync def handle_webhook(request):\n    body = await request.body()\n    signature = request.headers.get(\"X-Synapse-Signature\", \"\")\n    if not verify_signature(body, signature, WEBHOOK_SECRET):\n        return 401\n\n    event = json.loads(body)\n    if event[\"event\"] == \"memory.store\":\n        # Sync to another system\n        sync_to_external(event[\"data\"])\n    elif event[\"event\"] == \"chat.message_received\":\n        # Trigger agent wake-up\n        notify_agent(event[\"data\"])\n```\n\n## 次のステップ\n\n- [Cron & Scheduler](/docs/api/cron)\n- [Webhook Automation
